UN R48 Supplement 11 (06 series) · UNECE Regulation No. 48 (ECE R48) — Uniform provisions concerning the approval of vehicles with regard to the installation of lighting and light-signalling devices.
UN R48 — Supplement 11 to the 06 series of amendments
Supplement 10 → 11
- What changed
- New paragraph 2.37. defines the “external status indicator”, and new paragraph 5.32. gives the conditions to allow one, or up to two, on a vehicle.
- Under paragraph 6.18.9., an optional side-marker lamp on the relevant side may now be switched OFF while the direction indicator lamp is activated. This applies when it is grouped or combined with a position lamp that is reciprocally incorporated or grouped with the direction indicator.
- Paragraphs 6.2.9.2. and 6.2.9.3. now say “for each headlamp”, and paragraphs 6.3.6.1.2.1. and 6.3.6.1.2.2. say “for each front fog lamp”, for the luminous flux compared with 2,000 lumens.
- Why
- The expert from GTB proposed to harmonize the switching requirements for side-marker and position lamps when mutually incorporated.
- The expert from GTB also proposed correcting errors and discrepancies in the text of the 05 and 06 series of amendments to Regulation No. 48.
- The expert from OICA introduced a revised proposal which defined and described the operation of the external status indicator.
Q1What changed26 changes
External status indicator: new definition, and not a lamp (paras 2.7. and 2.37.)
New paragraph 2.37. defines “external status indicator”. It is an optical signal mounted on the outside of the vehicle. When the vehicle is parked, it indicates the status or the change of the status for Vehicle Alarm System (VAS), Alarm System (AS) and immobiliser. These are the VAS, AS and immobiliser of UN Regulations No. 97 and No. 116. Paragraph 2.7. now adds “external status indicator as defined in this UN Regulation” to the things that are not considered as lamps for this UN Regulation.
Conditions for one or two external status indicators (para. 5.32.)
New paragraph 5.32. allows one external status indicator for Vehicle Alarm System (VAS), Alarm System (AS) and immobiliser if three conditions are met. The light intensity in any direction does not exceed 0.5 cd. The colour of the light emitted is white, red or amber. The area of the apparent surface is not larger than 20 cm2. Up to two external status indicators are allowed on a vehicle provided that the apparent surface does not exceed 10 cm2 per indicator.
Optional side-marker lamp switched OFF with the direction indicator (para. 6.18.9.)
Paragraph 6.18.9. has a new sentence for an optional side-marker lamp that is grouped or combined with a position lamp. This position lamp is reciprocally incorporated or grouped with the direction indicator. The electrical connection of the side-marker lamp on the relevant side of the vehicle may then be such that it is switched OFF. This covers the entire period (both ON and OFF cycle) of activation of the direction indicator lamp. Two other sentences of paragraph 6.18.9. now write “rear fog lamp” and “rear direction indicator lamp” without a hyphen.
Apparent surface in the direction of the reference axis (paras 5.7.2.1. and 5.8.2.)
Paragraph 5.7.2.1. now covers single lamps “the apparent surface of which is composed of two or more distinct parts”. Before, it said single lamps “composed of two or more distinct parts”. Its subparagraphs (a) and (b) now refer to the distinct parts “of the apparent surface in the direction of the reference axis”. Paragraph 5.8.2. covers the minimum height in relation to the ground of a dipped-beam headlamp. This height is now measured from the lowest point of the apparent surface in the direction of the reference axis, independent of its utilization. Before, it was measured from the lowest point of the effective outlet of the optical system.
Visibility of red light towards the front and white light towards the rear (paras 5.10.1. and 5.10.2.)
Paragraph 5.10.1. covers the visibility of red light towards the front of a vehicle. The observer now moves within Zone 1 in a transverse plane situated 25 m in front of the vehicle (see Annex 4). Before, the text said “within Zone 1 as specified in Annex 4”. Paragraph 5.10.2., for white light towards the rear, now says “of a vehicle” and no longer says “fitted to the vehicle” after “white side conspicuity markings”.
Luminous flux for each headlamp and each front fog lamp (paras 6.2.9.1. to 6.2.9.4., 6.3.6.1.2.1. and 6.3.6.1.2.2.)
Paragraphs 6.2.9.2. and 6.2.9.3. cover dipped-beam headlamps with a light source or LED module(s) producing the principal dipped-beam. Both now say that the objective luminous flux which exceeds 2,000 lumens is the flux “for each headlamp”. Paragraphs 6.3.6.1.2.1. and 6.3.6.1.2.2. now say that the total objective luminous flux of the light source is “for each front fog lamp”. The provision that paragraph 5.5.2. does not apply to dipped-beam headlamps now has the number 6.2.9.1. Some sentences of paragraph 6.2.9. now say “principal dipped-beam” instead of “principal dipped beam”, and “UN Regulation” instead of “Regulation”.
Reference to UN Regulation No. 23 (para. 6.26.9.2.)
Paragraph 6.26.9.2. now refers to paragraph 6.2.2. of UN Regulation No. 23 instead of paragraph 6.2.3.
Q2Why it changed
- Proposed by
- Expert from the International Automotive Lighting and Light-Signalling Expert Group (GTB) (side-marker lamps and corrections); expert from OICA (external status indicator)
- Working party
- GRE, 79th session (April 2018)
Reasons
The proposal aims to harmonize the switching requirements for side-marker and position lamps when mutually incorporated. Increasingly, the design of modern vehicles has a tendency to have lamps that wrap around the corners. The case is an optional side-marker lamp grouped or combined with a position lamp reciprocally incorporated with the direction indicator. It is desirable to allow such a side-marker lamp to be switched off, in the same way as the position lamp. This is to improve the recognition of the direction indicator. There will be an increase of conspicuity of the direction indicator lamp signal, since only one colour will be seen.

Proposer's reason (informal document GRE-78-05)
For paragraph 5.8.2., the present wording “Effective outlet of the optical system” is not defined in Regulation No. 48. The new wording is aligned with the definitions of paragraph 2.9.1. For paragraph 5.10.1., the absence of the reference to the “transverse plane” could give interpretation problems. It was proposed to reinstate the original text as far as the “transverse plane” is concerned, as in paragraph 5.10.2. A small editorial change to paragraph 5.10.2. was proposed for the total alignment of the texts of the two paragraphs.

“5.8.2. (R48/06) The present wording “Effective outlet of the optical system” is not defined in UNECE-R48.”
“The wording in paragraph 5.8.2 is now aligned and coherent with the one used in the definitions of paragraph 2.9.1.”
“Since the absence of the reference to the “transverse plane” could give interpretation problems”
“it is proposed to reinstate the original text as far as the “transverse plane” is concerned, as currently existing in paragraph 5.10.2..”
“For the total alignment of texts of the two paragraphs the small editorial change to paragraph 5.10.2.is proposed.”
Proposer's reason (informal document GRE-78-05)
The changes to paragraph 6.2.9. are intended to make its interpretation indisputable, as far as the 2000 lumen limit application is concerned. An editorial revision was also proposed to separate the existing text into four sub-paragraphs, for better understanding. Paragraphs 6.3.6.1.2.1. and 6.3.6.1.2.2. are changed for the same purpose. Paragraph 6.26.9.2. corrects a wrong reference.

Proposer's reason (informal document GRE-77-25-Rev.2)
Based on the comments from the representatives of France, UK, Finland and Japan, the area of the apparent surface was lowered. For one indicator, it was lowered from 50 cm2 in GRE/2016/33 and GRE-76-17 to 20 cm2. If two indicators are installed, the area of the apparent surface should not exceed 10 cm2 per indicator.
